A plication filed November 21, 1925.

To (1U w/wm if may concern:

Be it known that l, dorm S. llunNniur, a citizen of the l nited State's, residing at lxiddetord, in the county of York and State of iine, have invented certain new and useful ln'iprovenients in Builder Mechanism For l finding leiachines, of which the following is a clear, full, and exact description.

This invention relates to builder mechanism for winding machines and with regard to certain more specific features thereof to a control device tor the gain and traverse of a ring rail. It is one of the objects of the present invention to provide a simple and very inexpensive device adapted for easy application to existing types of mechanism.

I am aware that various forms of control have been devised for regulating the speed and range of traverse and the amount of gain, and that means have been devised previously for modifying the control device to accommodate selectively a warp wind and a filler wind. But in all instances of which I am aware the modifying operation is diflicult and lengthy, sometimes requiring as much as three quarters of an hours time to make the necessary changes of pulleys and chains and other adjustments. By my invention a very simple form of control device suffices for either character of wind and there are no additional parts necessary for one wind which do not function and form a part of the control for the other wind. A

tion hereinafter set forth and the scope of theapplication of which will be indicated by the following claims.

In the drawings wherein is shown one of various possible embodiments of the invention:-

Referring now more particularly to the drawings,

A portion ot the spinnin machine tranie is indicated in Fig. 1 at 10. It comprises as the main elements an end standard 11 and a loiigitudinal or side beam 12. The latter has mounted thereon for rotation in the usual fashion a multiplicity of bobbin spindles 13 with which there is cooperatively associated a ring rail 14 of usual construction. The ring rail is connected by a litter rod 15 with a bell crank lever 16 pivotally mounted at 17 in a journal bracket 18 de' pending from the beam 12. It will be understood of course that this litter rod and bell crank lever mechanism is illustrative of a number of similar constructions successively positioned along the machine and connected each to the other by bars 19. A lever 20 evtends on the opposite side of the shaft 17 from the lifter rod 15 and this lever is weighted as indicated at 21 to overbalance the weight of the ring rail. lifter rod, lever. etc., on the opposite side of the fulcrum 17. As is usual in machines of this class the action of the weight on the ring rail is opposed by certain chains and connections which extend to a builder mechanism indicated generally at 22. Any of the usual types oi builder mechanism may be employed, and it is therefore unnecessary to describe in detail the construction and arrangement of parts of this mechanism. The actuating cam for the builder mechanism is shown at 25 journaled in the end standard 11 and driven at a slow rate of speed through suitable reduction gearing, not shown. This actuating cam governs the traverse of the ring rail, and it suitable for filler winding may be supplanted by another cam when desired to effect the longer traverse of a warp wound bobbin.

The present invention resides in the gain control drum and cradle about to be described. Extending inwardly from and mounted upon the end standard 11, there is gain cona bracket having depending journal arms 31 and 32. A cradle 33 is provided with short cylindrical machined bosses 34 and 35 adapted to drop into the journal arms 31 and 32 of the bracket so that the cradle 33 will be supported with a capability of pivotal movement about a horizontal axis. The cradle or cradle box 33 is suitably recessed on opposite sides as indicated at and 41 to receive a shaft or pintle 42. A triple tread pulley or drum 43 is loosely ar ranged on the shaft 42 so that it may have a rotative movement thereon.

As shown clearly in Figs. 5 and 6 one tread of the pulley 43 is chordally flattened at 44. The purpose of this cut-away or flat of the tread 45 is well understood by those skilled in the art. This tread 45 with its cut-away 44 is for particular service in filler winding where the amount of gain in the early stages of the winding operation is comparatively small, the amount being subsequently increased as the range of traverse moves upwardly with relation to the bobbin. The parts associated as shown in Figs. 1, 4, and 5. are for use in efiecting the filler wind of the bobbins. Referring again to Fig. 1, there will be noted a segment movable with the bell crank lever 16, and having fixed thereto a chain 51. This chain passes over the drum 43 in the plane of the tread 45, and in the early part of the winding operation the chordal fiat 44 of the drum is functioning so that the gain of the initial traverses of the ring rail is very slight. The end of the chain 51 is secured to the drum 43 by a suitable screw or bolt as indicated at 52. A central tread of the pulley 43 is indicated at 53, and there is also another tread 54, the purpose of which will be set forth presently. A chain connects the pulley 43 with a pulley 06 of the actuating mechanism 22. This chain has a suitable swivel connection 57. To compensate for the non-parallelism of the axes of the two pulleys 43 and 56, one end of the chain 55 is brought around the tread 53 of the drum or pulley 45 and is secured as shown in Fig. 5 by means of a suitable screw or bolt 60. The other end of the chain 55 is secured to the tread of pulley 56. The treads 45 and 53 are utilized in securing the gain control for filler winding. hen it is desired to change over to the operation of warp winding it has been necessary heretofore to make extensive changes and chain adjustments sometimes with the alteration of the entire cradle, sometimes by the addition of parts, and in every instance the modification of the gain control to secure the different character of operation has been lengthy and inconvenient. According to the present device, it is only necessary to remove the pulley 43 and the shaft 42 from the cradle 33, reverse the pulley and shaft, and return them to the cradle 33 as shown in Figs. 2 and 3 of the drawings. The chains 51 and 56 having been disconnected are then restored and attached to the drum. The chain 56 will find its position over its former tread 53. The chain 51 will be arranged in position. over the tread 54 which was inoperative during the filler winding operation. The arrangement of the cradle 33 for pivotal movement on the bracket permits the chains to follow at all times in their designated treads irrespective of variation of the position of pulley 56.

lVhat I claim is 1. A gain control device for winding n1achines comprising a triple tread reversible pulley or drum, one tread being flattened to serve in the filler winding operation, and means rotatively supporting the pulley and permitting its reversal to eliminate the flattened treadso that the other two treads may be employed as in warp winding.

2. A gain control device for winding machines comprising a bracket, a cradle pivotally mounted on the bracket and a triple tread pulley or drum having two continuous circular treads and another tread of part circular form with a chordal fiat, means rotatively supporting the pulley in the cradle, said means permitting removal, and reversal of the pulley to eliminate the flattened tread and substitute a complete circular tread.
